Thursday evening

It's getting cold and I need.. do I really need to know all this? Why so muchhhhhhhhh technology. Is it really so good to have the technology we use change and update monthly????? Who are these third party holders of MY data and YOURS? My pictures in Picasa, others on Facebook, my gmail account seems to automatically know everyone I ever emailed or who ever emailed me when I use one of their linked applications. .... But, I want to know, understand, and even use the resources out there.
